To all whom t may concern.'

Be it known that I, WALTER lV. CHAMBER'- LAIN, a citizen of the United Statesresiding at lllttertown, in the 'county 'of Jefferson and State of New York, have invented certain new and useful Improvements in Carton Fillers, of which the following is a specilicat-ion. y This invention relates to carton ,illers, 'dell signed particularly for use by confectioners, and the like, for vfilling cylindrical Acartons with ice-cream, and other produ-cts, and has for its object to provide novel and sanitary means for filling the cartons at a. single 125 operation. A further object is to providea hollow cylindrical bo'dy for in'closing and holding the 'cartons during the filling operation, the said body being'equipped `with a handle by whichthe device is manipulated, 2l) and the said handle and `body being separa.- ble for facilitating the applying and removing of the cartons. And a further object is to provide means for preventing the over-filling and fouling of the cartons.

I attain these objects by the vmeansvset forth in the detailed description which follows, and as illustrated by the accompanyinv drawings, in which'- Figure l is an elevational view of the 30 complete device, showing the handle locked to the body ready for filling a carton. Fig. 2 is a lcentral vertical section, in which parts of the carton are broken away to show the extent of the filling. Fig. 3 is a top-plan view of the device. Fig. 4 is a horizontal section, taken on line 4 4 of Fig. 2. Fig. 5 is an elevational view, showing the handle and body separated. Fig. 6 is a view, showing the body partially inverted and the carton gravitating therefrom. And Fig. 7 is a detached view of the filled carton.

In the drawings, 2 represents a hollow c vlindrical body preferably open at both ends, the lower end of which is provided with a circular row of teeth 2', by means of which the body, when rotated like an auger, cuts its way into the more or less solid ice-cream, which is usually kept in relatively large freezers or cans (not shown). The top end of the body 2 is closed during the filling operations, by a cap 3, the latter having a depending flange 3', which receives the body, and may be temporarily locked thereto, by means of pins 2a, which project from the opposite sides of the body, and corresponding angular Slew 3, Whll. are .fOr-ined in. the

free margin of the said lflange '(see Figs. l i 2' and 5). The top ofthe caoB is formedwith a 4'concentric hub 'or sleeve 3", which receives the lower 'end of the stem 4, of 'a 'T-han'dle 4, by means of which the device is manipulated duringfthe filling of the cartons. VT'lre stem 4 `may be rigidly se'c'ured to the hub by a pin 3 Preparatory to filling the vordinary cylindrical carton, as 5, the cap `and handle 4 are removed from the bo'dy2, as

placed -and'locked to the body, as shown in F l and 2. In Aorder to prevent the endwls'e movement of the carton 5, during the lling'operation, a shoulder 3 ofthe 'cap is 7 arranged to normally bear against the bottom end'of the carton, as shown in Fig. The slots v3 and the pins 2aa're arranged to prevent the accidental separationv of the 'cap 3 and the body 2, 'during the filling operation. The rib 2h, in addition to stopping the downward movement of the carton, also serves to seal the joint between the carton and the inner surface of the body 2'," and prevents any of the ice-cream or other product, from reaching and fouling the said parts.

follows: Assuming that the device is loaded with an empty carton 5, and the cover 8 is locked in place, as shown in Figs. l and 2, the operator grasps the handle 4, and holding the device, as shown in Figs. l and 2, in-

serts the body 2 into the ice-cream container (not shown), until the normally open lower end 2 of the body contacts with the ice-- cream. The operator should then exert downward pressure on the filling device, and at the same time twist or rotate the body 2, like an anger, for boring downwardly into the frozen cream, until the flange 3 I of the cap sinks substantially its full depth into the ice-cream, which indicates that the carton is filled. Ordinarily, the carton 5 will ll properly at a single operation, provided the requisite pressure is exerted, but,

in order to obviate the danger of the imperfect filling of the carton, dus to the pres- The operation of my carton filler, is as ence of air that may be confined in its top or closed end, I provide simple means for venting lthe carton, which consists of a tapering tube 6, that depends from a bridge 6 carried by the cap 3'. The free end of this tube is preferably sharp enough to readily puncture the bottom 5a ofthe carton (as shown in Fig. 2), by the force exerted in applying the handle to the body 2. By this arrangement, any air that may become entrapped in the carton will be readily forced upwardlythrough the vent 6, and finally escape through a small opening 4a of the stem 4. VAfter the carton 5 is filled, as explainecbthe device is'withdrawn from the main container, and the cap 3 is removed from the body 2, by the turning of the handle 4 in the opposite or leftward direction, for freeingthe pins 2a from .the slotsBf. The body 2 should then be inverted, as shown in Fig. 6, for allowing the release of the filled carton, which is usually effected by gravity. A particular aim of the present invention, is to substantially lill the cartons, and to prevent any of the icecream from showing beyond the level or plane of the mouth 5b of the carton, when the latter emerges from the body 2. To this end, I provide a wire or cut-off which .is preferably disposed diametrically across-the interior of the body, substantially in the plane of lthe' mouth 5b of the carton,v as shown in Figs. l, 2, 3, and 4. The wire 7 is preferably of small gauge, so as not to interfere with the boring and filling operation, and during the final rotary movement of the body 2, the wire 7 gauges the filling of the carton., rby cutting the ice-cream level or flushwith the mouth of the carton, as best shown in Figs. 2 and 7 The provision of the wire 7 not only obviates waste of the icecream by over-filling the carton, but also prevents the cream from smearing and fouling the interior of the cap 5 of the carton.

Obviously my device may be employed for 'filling cylindrical cartons with butter, lard, and other products 0f like consistency, as well as ice-cream; the construction', arrangement and operation of the device being such that, any person of ordinary skill may apply, fill and remove the cartons in a ready and sanitary 'mannen and at a single operation.

Having thus described my what I claim, isy l.` A carton filler comprising a cylindriinvention,

calbody open at both ends and formed at y one end with a cuttingV edge and an inA wardly set, inwardly pressed bead,`the latter forming a stop shoulder for a carton inserted from the opposite end of the body, a

cutting wire-stretched across the firstendl of the body and having its ends secured to the bead, a removable vcap closing the said opposite end of the body and formed with a central sleeve, a piercing prong supported at the base of the sleeve, and a hollow han-y dle secured in the sleeve and provided with an airvent.

2. A carton filler comprising ka body .open at -both ends for receivinga carton, a removable cap for closingone end of the body having a marginal 'fiange encircling the body and detachably connected therewith, and a piercing prong arranged within the cap and above the lower edge lof the angewhereby the prong is protectedv and concealed by said flange whensaid cap is removed and resting onk lits flange. l
